Technologies are evolving and the equipment working on sensors becomes more popular with every year, as they are faster, handier and more environmentally friendly. Portative spectrometer CL-710 CID Bio-Science allows analysing spectrum of 350–1000 nm and rapidly estimates vegetation properties. For crop farming in greenhouses, farmers more often choose to use LED (light emitting diodes). Red, blue LED and natural light was used to grow tomatoes’ plants in polycarbonate greenhouse of Latvia University of Agriculture. The aim of the study was to evaluate most appropriable indexes for characterisation of tomatoes’ growth in different illumination conditions. Results showed that the unique and the most appropriable indexes are FRI, NPCI, PSRI, WBI and G. Larger differences were observed at plants flowering stage.
